PureFlo® PES Mini filter cartridges from JALT Technologies (Manassas, VA) are highly retentive hydrophilic polyethersulfone (PES) membrane filters in an all-polypropylene construction for chemical compatibility. The membrane does not require pre-wetting with IPA or flushing with DI water. They also reduce potential for bubble formation by not de-wetting in outgassing fluids. They are suitable for critical applications that require particle removal efficiency of 0.04, 0.1, 0.2, 0.45, 0.65, 0.80, and 1.2 microns. The cartridges are available in lengths of 1.5, 2.5, and 5”, with a 2.2” diameter. They feature an effective filtration area of 0.78 ft2 for the 1.5” length, 1.3 ft2 for the 2.5” length, and 2.6 ft2 for the 5.0” cartridge.
